To all when it may concern:

lie it known that I, Enoaiu Vltzll, a resident of Washington, in the county of Washington and State of Pennsylvania, have invont'ed a new and useful Improvement in Com oaitiona whic the following is a specification.

This invention relates to a compound or composition for removin and preventing inerustationa in steam an hot water boilers, hot water radiators, cooling pipes for gas engine cylinders, and the like, and is an improvement iipon prior computations for this iur I latent No. 824412 of June 26, 1906 to Jacob R. Greene, Jr. deacribm a certain compound or compoaitiou for removing or preventinf incrustations in steam boilers and the lit other impurities contained in the water. The compoaition deacribed in said patent conainta ol coflee, balaam weed, yarrow and powdered graphite. The. composition deacri in said patent has given very sat sfactory reaulta in actual uae, but I have dismade more rapid and dlcient the addition. of other ingredients: to t one above named. From actual teata l have found that the addition of tobacco and ordinary Epaom aalta oonaiderably ini roves the action of the ingiedienta named n aaid Greene iateiit. The improved compoaition as I uive found it best adapted. for thin pur conaiata of the following inradianta, an in auhatantially the proportion atatad, to-wit;

reen coilee ten pounda, one ipaoinaaltaoneounmlialaainwaadone ounce, yarrow one ounce, and graphite one ounce. The eolea ia, aa atatad. Greene patent,preterably uaad in the iinroaatad term that a while green. The M may be of any character, preferably the waata portiona from c r an other factorial, or or that matter obacco which i practically I Had, but which oontaina the active 1 ienta.

. This eompoaitioncan be formed as stated in the Greene patent with the ingradienta in a fairly fine condition, and il preferably need for Cleaning Boilers, of'

e due to mineral matters and cipal ingr i o in the same manner as there stated, that is, inclosed in a fabric casing and then introduced into the boiler where it will remain in a mass so that the active ingredients tllt leeched out slo vly and the eliiciency of the compound extended over a considerable period of time.

Actual use of the composition above described has given very excellent rcanlts. The composition has thoroughly cleaned boiler tubes which have been so badly iiicruated that it was not possible to clean the same in any other way, and which were in such condition that the tubes were conaidercd to be practically ruined. My improved connioaition has not only quick y softened up the do coils and incrustntious so that they could washed out, but so thoroughly cleaned the metal that further-corrosio; thereof has been practically stopped.

What ,1 "laim is:

l. A composition for ireventin and re moving iiicruktationa in ioilers an dike de-' vices liavizig coffee and tobacco as its prim icnta.

2. A composition for preventing and removing incruatations in boilers and the like, having coffee and tobacco an ital grinci al in gredienta and also containing ipaon tllltl.

3. A composition for preveutin and removing ingredients in boilers am the lik consisting of cottee, tobacco, balsam weed and Epeun salts.

4. A compoaition for preventi and removing incrustations in boilers am the like, having notice and tobacco an its principal ingredienta llitlttlnu containing pulverized graphite.

5. A compoetiou forpreventi and removing incrustnflons in boileraan the like, consisting of eollee, tobacco, balsam weed Epaom saint, graphite In tea'tuuony whcreofll have hereunto not my hand.
